Except putting the tools in the game doesn’t make them easier to use - it only maybe makes them more likely to be stumbled upon. The number one way to improve the new player retention rate among those who are actually interested in EVE is to improve the NPE itself and do a better job of explaining core game mechanics, followed closely by do a better job connecting players socially to others who are interested in helping them learn and grow in EVE.
Neither of those requires moving the tools inside of EVE - both are focused on improving communication of information to new players. Whether the tools are inside the game or not is irrelevant to disclosing the existence of supportive content and helping new players engage with it.
